The only issue I have with it is dependant on your layout I'd have to leave equipment in front garden for prospective buyers to inspect ... Being in Essex I'd be worries that they'd just grab it and run 😄 I can safely say I wouldn't chase them !
-
The backlash I can feel is in Ra though ?
-
Thanks Michael, it's a brand new mount, cant feel any backlash (slight on Ra) I'm wondering if the fact that It kept losing the guide star might be the culprit. Another night of explaining to Mrs Knobby that 'no I haven't taken any pictures' just dabbling !

Oops, well spotted @michael8554, I'll post guide log later. No ST4, windows Synscan app (don't like EQ mod ) pulse guiding EDIT - attached guide log PHD2_GuideLog_2020-05-19_221608.txt

Thanks @wimvb I guess I'll have to have a dabble again next clear night. Just weird though.

Hi All, wondered if you could help me make sense of this ... new HEQ5 - belt modded by FLO, all feels good, minuscule backlash but strange guiding. Admittedly first time using it but baffled. Failed calibration see image below and guiding seemed to be Ra and Dec following each other. Stars look ok ish (@ 1500 mm ) Needle galaxy is poor as only about 10 mins each in RGB note - it was hazy and did keep losing star in OAG Thanks for looking PHD2_DebugLog_2020-05-19_221608.txt

What are you thinking, A minor ... B flat ?

It's not the wrong way round, he's checking to see if he has wet himself 🙂
-
No criticism Steve but your stars appear to have a weird diffraction - see attached. Looks like something in light path maybe ? do you have any screws maybe too long. Shine a torch inside to check. I know we've talked about this before but I've never noticed it. Any ideas anyone ? Enlarged 300 % to show effect - lovely round stars by the way !

Optical weirdness - Off Axis Guider abberations
knobby replied to RyanParle's topic in Discussions - Scopes / Whole setups
No idea really but have you tried moving the stalk / prism further in towards edge of chip ? Blow everything out with blower brush ( hair or eyelash in path ) rotate guide cam to see if pattern moves to see if camera or oag ? -
Looking good 👍
-
Nice ! you've got NGC 6207 in there too (I think) Down a bit and left a bit
-
Probably loose / poor soldering inside ... just pull it apart and have a looky

Had a great night imaging remotely again last night ( courtesy of @Blazar and anydesk ) despite several hiccups, a couple of changes of plan and some ascom issues we managed to align and plate solve successfully. Gave up on ascom and used the Celestron CPWI software (excellent by the way) and after all sky plate solve wouldn't detect focal length, went with ASTAP ( which I use and trust ). 90 minutes into session we had M13 dead centred and I left Steve doing 3 minute subs with excellent guiding and cuddled up to Mrs Knobby to watch some telly. No pressure Steve but show us the result !

Star link and the damage to the night sky?
knobby replied to hawksquawks's topic in The Astro Lounge
Disgrace, absolute disgrace. Can't believe he's been allowed to do it 😣 -
Star adventurer counterweight kit with and M8 to M12 (if i remember correctly) adaptor, but the EQ1 kit fits from what I gather if you can find one. A lot of people just buy threaded rods ! Useful info here https://www.cloudynights.com/topic/661513-skywatcher-az-gti-useful-links-and-accessories/

@Blazar It was a pleasure, felt a bit like imaging on a remote telescope in some far flung dark observatory 🙂
-
Hi John, good to see some new activity on the Essex group 👍 how are you imaging ?
-
Looking good ! and very colour coordinated too 🙂
-
Personally I love mine but you do read lots of horror stories about backlash etc. If you do get one get it from FLO as you may need to return it. Remember it wasn't designed for imaging or EQ use but Skywatcher gave us a custom firmware to enable it. Attached images are 300 second guided narrowband over 2 nights. FLO sell a cable which allows direct connection to mount so no WiFi worries. Haven't tried unguided though. Manfrotto tripod/Skywatcher wedge/finder guider/Sharpcap polar align. Scope image is out of date as I'm dabbling with OAG and have an extra counterweight to balance better.

Synscan 4.390400 issue with AZ GOTO Skywatcher telescope
knobby replied to Gevorg's topic in Discussions - Mounts
What is the spec of the 12 v adaptor ? -
Interesting dilemma ... You state that you're thinking HEQ5 further down the line so any mount you buy will be a stop gap. Maybe consider an AZ-GTI / wedge etc as it's super portable for your trips to dark sites and will carry your 72ed nicely, it can also guide via the Synscan app. Worth looking at and cheaper too !
-
Translation by Google ... I joined the sensor breakers club !!!. It is a Nikon D90. I broke his sensor trying to break the glass. I'll buy another one. But I need more information about the intervention on the Nikon D90. I want to add cooling to the sensor since I have it disassembled and I want to do everything I can to make it monochromatic and long exposure. Thank you for all the information provided.

Feel for you ... I've got one on order with @FLO, they were honest (as usual) and did say it could be delayed. Also said they'd wipe it down with alcohol to make sure it was Covid free 😁
-
No guide port but I guide using the Synscan pc app. Works on WiFi or cable to mount. Same as ascom pulse guiding (sort of)
